Keep the coil parallel to the ground. At that height, your
detector will not be affected by the ground mineralization. As
you lower the coil, the detector will read the ground matrix and
let you know how to adjust to achieve aground balance. (Note:
You must lift your coil straight up.
Do not
swing it like a
pendulum.) Once you have got a steady threshold, quickly lower
the coil straight down to approximately 1 inch off of the ground
and listen to any change that may occur in the threshold. You
will hear one of three sounds: 1) the threshold will get louder or
go positive 2) the threshold will go quiet or become negative, or
3) the threshold will stay the same.
If the threshold stays the same, the detector is telling you that
the ground matrix is not affecting it and you are ready to hunt.
If you get a positive or negative signal, the machine is telling
you that it is being affected by the ground matrix and must be
adjusted for peak performance.
If your threshold goes positive, you must turn the GROUND
ADJUST knob counterclockwise or towards the negative side.
If your threshold goes negative, you must turn the GROUND
ADJUST knob clockwise or towards the positive side.
Once you have made an adjustment, lift the coil up, let the
threshold retune and push the coil down again while listening
for any sound change as the coil drops. If there is a threshold
change, follow the above directions and repeat until you have
very little or no threshold changes on the way down. A very
slight positive response is better than any kind of negative
response.
Once you have got a steady
threshold, quickly lower the coil
straight down to approximately 1
inch off of the ground.
If there are threshold changes on the upstroke do not pay attention to them. As you raise the coil, the
detector goes from a ground matrix (soil) to no ground matrix (air) and that difference will most likely
cause some change in the threshold tone. Only changes on the downstroke are to be adjusted for.
Now that your detector is ground balanced, you are ready to hunt. You can stay in either of the ALL
MET Modes or switch into the
MOTION DISC.
Whichever mode you choose to hunt in, it is always
necessary to ground balance in an ALL MET Mode first.
Just like any skill, ground balancing must be practiced constantly. The easiest place to do it is in your
backyard or any place close that has at least a 10 foot by 10 foot area. First, check for any metal targets
and remove them. When the area is clean, take your Tiger Shark and ground balance it. When you are
done, spin the GROUND ADJUST knob either positive or negative and ground balance again. Keep up
this practice until you feel comfortable with ground balancing. Take some time to keep your ground
balancing skills sharp and you will see better results in the field.
SELECTING THE RIGHT SEARCHCOIL
Selecting the right searchcoil for the type of detecting you're doing will add greatly to your success.
In addition to the standard 8 inch open center searchcoil, two optional coil sizes are available for the
Tiger Shark. The 10 1/ 2 inch open center coil is designed for areas where digging is easier and where
junk targets may not be too numerous. The 7 inch coil will be particularly useful when searching for
smaller targets, such as gold nuggets.
